SCIENCE.4.6.C — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

S.4.6.B

investigate and compare a variety of mixtures, including solutions that are composed of liquids in liquids and solids in liquids; and

S.4.6.C

demonstrate that matter is conserved when mixtures such as soil and water or oil and water are formed.

S.5.6.B

demonstrate and explain that some mixtures maintain physical properties of their substances such as iron filings and sand or sand and water;

S.5.6.C

compare the properties of substances before and after they are combined into a solution and demonstrate that matter is conserved in solutions; and

S.6.6.B

investigate the physical properties of matter to distinguish between pure substances, homogeneous mixtures (solutions), and heterogeneous mixtures;

S.7.6.D

describe aqueous solutions in terms of solute and solvent, concentration, and dilution; and

S.7.6.E

investigate and model how temperature, surface area, and agitation affect the rate of dissolution of solid solutes in aqueous solutions.

S.8.6.A

explain by modeling how matter is classified as elements, compounds, homogeneous mixtures, or heterogeneous mixtures;

IPC.7.F

plan and conduct an investigation to provide evidence that the rate of reaction or dissolving is affected by multiple factors such as particle size, stirring, temperature, and concentration.

CHEM.11.A

describe the unique role of water in solutions in terms of polarity;

CHEM.11.B

distinguish among types of solutions, including electrolytes and nonelectrolytes and unsaturated, saturated, and supersaturated solutions;

CHEM.11.C

investigate how solid and gas solubilities are influenced by temperature using solubility curves and how rates of dissolution are influenced by temperature, agitation, and surface area;

CHEM.11.D

investigate the general rules regarding solubility and predict the solubility of the products of a double replacement reaction;

CHEM.11.F

calculate the dilutions of solutions using molarity.

AQUA.7.C

identify variables that affect the solubility of carbon dioxide and oxygen in water;

Cross-curricular Connections

The cross-curricular connections are designed to help educators make content connections between the science TEKS and math, English language arts and reading, social studies, and technology applications. The standards below illustrate alignment between grade level content areas which may help educators develop cross-curricular lessons. These connections do not represent all possible connections that might be made.
